Whether you are a beginner or a seasoned IT professional, this guide will provide you with detailed steps, examples, and best practices.

What is a Distribution List?

A distribution list (DL) in Exchange Online is a group of email addresses that allows you to send emails to multiple recipients simultaneously. Instead of typing each recipient’s address, you can simply type the distribution list’s name. This feature is especially useful for teams, departments, or projects.

Why Use Distribution Lists?

  1. Efficiency: Sending a single email to a group saves time and ensures everyone receives the same message.
  2. Organization: Keeps your email system organized, especially for large teams.
  3. Collaboration: Facilitates easy communication among team members.
